Naruto is one of my favorite anime, but the filler is crap. Forgive my sincerity and rawness hahahahaha.
I was hoping that in Obito's flashbacks we would see Minato's strength for example, and why he was feared in the ninja world, but fuck. There was nothing good there.
Plus we see that the fourth ninja war was only about Rin, not very argumentative. No logic, I explain.
